If SE is going the way of the arena combat, it's mechanics are absolutely nor fit for purpose as of now. The two biggest problems are the complete incompetence of defensive turrets1 and your absolute dependency on exposed, fragile equipment. If you start without spare parts, if any player sneak2 in and grind 10% of either your starting generator, assembler, refinery or, to some extent, suit power supply, you're done, nothing you can do.
I think the best way SE could handle arena-style survivals would be to make sure teams start in heavily, and I do mean heavily, fortified positions. Something that can effectively cover vital components and ward off early assaults while everyone get production going. Early combat would consist of trying to take down mining craft wandering away from the bases' cover and would lead up to organized strikes with large ships backing up attack crafts.
Now that's something I'd like. And it would be possible if turrets weren't such terrible shots1.
1 Point-perfect accuracy only mean they miss reliably.
2 Stealth not actually required.
